I don't know why it happened, since it doesn't appear to have happened to anybody else, but the sounds would play repeatedly hundreds of times rather than just once. The game was very fun, but I would advise you to maybe find out what is going on.
I can also say firmly that everything can go wrong when you blast, and I found out the hard way that it's best not to blast, ever. Which is a shame, since it seems like a very interesting mechanic, but every time I tried it, I would almost fly.
Nice job, great visuals, and good gameplay, but unfortunately, I can't really rate the audio...
